Rogers RO4350B™ High-Frequency Laminate Description
Rogers RO4350B™ is a glass-reinforced, hydrocarbon/ceramic thermoset laminate engineered to combine RF performance with FR-4 process compatibility. It bridges the gap between standard FR-4 and high-end RF materials, offering exceptional electrical stability and cost efficiency for wireless applications. Key properties include:
Optimized Dielectric Properties: Stable relative permittivity (Dk = 3.48 ±0.05 @ 10 GHz) and ultra-low loss tangent (Df = 0.0037 @ 10 GHz), minimizing signal loss.
FR-4 Process Compatibility: Compatible with standard multilayer PCB fabrication processes (drilling, plating, etching) and lead-free assembly, reducing manufacturing costs.
Thermal Reliability: Low Z-axis CTE (32 ppm/°C) and high thermal conductivity (0.69 W/m/K) prevent delamination during thermal cycling.
Flame-Retardant: UL 94 V-0 rated for safety-critical applications.
Moisture Resistance: Very low moisture absorption (0.06%), ensuring stable performance in humid environments.
Halogen-Free: Compliant with RoHS and IEC 61249-2-21 environmental standards.
Consistent Impedance Control: Tight Dk tolerance (±0.05) enables precise high-frequency signal integrity.
Primary Applications:
Wi-Fi routers/access points (2.4/5/6 GHz)
Cellular infrastructure (4G/5G antennas, small cells)
Automotive radar/sensors (24 GHz, 77 GHz)
IoT devices and RFID systems
Satellite communication terminals
General-purpose RF/microwave circuits
